For best results, add to water flow.Tip: pH UP works by slowly neutralizing acidic substances that cause low pH in pond water. Itâs important to test the pH when using pH UP. pH should be raised no more than .5 units every 24 hours. Do not treat the pond more than once every 24 hours. Plants and algae cause a temporary increase in pH in the afternoon; therefore, pH should be tested in the morning to obtain the lowest reading.Caution: Some fish may be sensitive to pH adjustments greater than 0.2 in a 24-hour period, so changes of this magnitude should be done with extreme care.
